./venv/bin/pip install .
51
```

6. Run uwsgi listening on the localhost port 8080
54
```bash
55
export OTTERWIKI_SETTINGS=$PWD/settings.cfg
56
./venv/bin/uwsgi --http 127.0.0.1:8080 --master --enable-threads --die-on-term -w otterwiki.server:app
57
```
58
59
7. Open `http://127.0.0.1:8080` in your browser.
60
61
8. Register your account. The first account is an admin-account with access to the application settings.
62
63
9. Alternatively can you configure the application using the settings.cfg. For all configuration options please see Configuration.
64
65
10. Create a service file e.g. `/etc/systemd/system/otterwiki.service`
66
```

Make sure to adapt the /path/to and that the configured user can read and write the database and the repository folder.
81
82
11. Run `systemctl daemon-reload` and `systemctl start otterwiki.service`, check `systemctl status otterwiki.service` for errors.

Note
85
It's highly recommended to use a webserver as reverse proxy to connect to uwsgi, see Reverse Proxy below.
86
:::
87
88
If you want to skip the reverse proxy consider to bind uwsgi not to just the local ip `127.0.0.1`, but to all ips of the host running An Otter Wiki with `--http 0.0.0.0:8080`.
89
90
# Reverse Proxy
91
A reverse proxy is a server that sits in front of web servers and forwards client (e.g. web browser) requests to those web servers. They are useful when hosting multiple services on a host and make it much easier to configure https. Neither An Otter Wiki itself nor the in the docker image provides https.
92
93
Mini how-tos for configuring Apache, NGINX and Caddy are provided below. For more detailed informations please check the corresponding software documentation.
94
95
Also check out Configuration for additional info on passing real IPs to the wiki.
96
97
## NGINX
98
This is a minimal example of a config that configures NGINX as a reverse proxy. The full documentation about NGINX as reverse proxy can be found here.
99
100
It's assumed that An Otter Wiki is running either in a docker container or as a uwsgi process and listening on port 8080.

```

}

```
117
### NGINX on Debian, Ubuntu and derivates
118
Install nginx via apt install -y nginx
119
- Create the `otterwiki.conf` in `/etc/nginx/sites-enabled/`
120
- Check the syntax via `nginx -t`
121
- Restart nginx via `systemctl restart nginx`
122
- Open http://wiki.domain.tld in your browser
123
- Check `journalctl -xeu nginx` and `/var/log/nginx/error.log` for errors.
